DETAILED DESCRIPTION

[0059] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0060] The present application provides a laundry treating apparatus (not shown in the figure), which refers to an apparatus for washing, cleaning, softening, drying, and removing wrinkles on clothes in a household or laundry shop. It includes various types such as a washing machine, a dryer, a washer-dryer, a clothes care machine, and a steam ironing machine, etc. The main function of the laundry treating apparatus is to provide a solution for clothes cleaning and drying, and to maintain the cleanliness and neatness of clothes through different programs and functions such as washing, rinsing, dehydration, drying, or care.

[0061] The laundry treating apparatus of the embodiments of the present application is described with a washing machine as a specific application example, and the technical solution is also applicable to other types of laundry treating apparatuses, such as a dryer, a washer-dryer, etc. Other types of laundry treating apparatuses can be adjusted and improved according to their own structural and functional characteristics, with reference to the embodiments.

[0062] The laundry treating apparatus includes a cabinet (not shown in the drawings) and a drum assembly (not shown in the drawings), wherein the drum assembly is rotatably disposed in the cabinet, the cabinet is a shell of the laundry treating apparatus, usually made of metal or plastic, capable of providing support and protection for the internal structure thereof, preventing it from being damaged by the outside. The drum assembly can include an outer drum and an inner drum disposed in the outer drum, the inner drum being a rotatable cylindrical structure, having a laundry treating cavity for accommodating laundry, water and detergent to achieve washing and drying of the laundry.

[0063] Referring to Figure 1 , the laundry treating apparatus further includes an automatic dispensing member (not shown in the drawings), which includes a dispenser box (not shown in the drawings) and a dispensing device 100 connected thereto, the dispenser box and the dispensing device 100 can be both disposed in the cabinet, or one of them can be disposed in the cabinet and the other can be disposed outside the cabinet; the dispenser box can be provided with a plurality of liquid storage cavities (not shown in the drawings), which can be understood to be independent of each other and can be used to store different laundry treating agents, such as laundry detergent, softener, fragrance, bleach, etc., and the dispensing device 100 can suck laundry treating agents from different liquid storage cavities and deliver them into the laundry treating cavity.

[0064] In some embodiments, the drum assembly can include a plurality of laundry treating drums, and different laundry treating drums can treat different laundry, thus requiring different laundry treating agents, such as, some laundry treating drums treat baby laundry, thus requiring baby laundry treating liquid; some laundry treating drums treat socks and other laundry, thus requiring deodorizing liquid; some laundry treating drums treat large laundry, thus requiring perfumed or other special care liquid, and so on. In this case, a plurality of liquid storage cavities are required, which can be independent of each other, partially independent, or shared for different laundry treating drums.

[0065] The laundry treating apparatus further includes a controller (not shown in the drawings), which can control the dispensing device 100 to start or stop sucking and dispensing laundry treating agents at specific time points according to a preset program or an external signal. The laundry treating apparatus provided with a plurality of liquid storage cavities can automatically dispense corresponding laundry treating agents according to the requirements of different stages and timing of laundry treating. For example, during the washing stage, the dispensing device 100 can suck laundry detergent and deliver it into the laundry treating cavity; after the washing is completed, the softening stage is entered, the dispensing device 100 can suck softener and deliver it into the laundry treating cavity; finally, before the drying of the laundry is completed, the dispensing device 100 can suck fragrance and deliver it into the laundry treating cavity, so that the laundry has a pleasant fragrance.

[0066] It should be noted that the controller can identify each independent liquid storage cavity, ensuring that the dispensing device 100 accurately extracts the corresponding laundry treatment agent from the corresponding liquid storage cavity during different stages of laundry treatment, such as washing, softening, and fragrance stages. The controller receives the working state information of the dispensing device 100 through sensors or data feedback lines, including the type of laundry treatment agent currently being extracted and the source liquid storage cavity. The controller also includes a control panel that can display the current processing status of the laundry treatment device, such as the type of laundry treatment agent being used and the corresponding liquid storage cavity number, so that the user can understand the processing process.

[0067] Please continue to refer to Figure 1 , specifically, the dispensing device 100 includes a pump housing 10 and a drive assembly 40, the pump housing 10 is connected with at least one liquid suction nozzle 20 and a liquid discharge pipe 30, that is, the liquid suction nozzle 20 can be provided with multiple liquid suction nozzles 20, and the multiple liquid suction nozzles 20 are one-to-one corresponding to the multiple liquid storage cavities, increasing the flexibility of the dispensing device 100. The multiple liquid suction nozzles 20 are all connected with the liquid discharge pipe 30, the liquid discharge pipe 30 is connected with the laundry treatment cavity, and the liquid discharge pipe 30 can directionally discharge the laundry treatment agent extracted by the different liquid suction nozzles 20. Since only one liquid discharge pipe 30 is provided, it is more convenient to control the flow direction and position of the laundry treatment agent.

[0068] Understandably, compared with the design of multiple liquid discharge pipes 30 in the related art, the multiple liquid suction nozzles 20 share one liquid discharge pipe 30, which simplifies the complexity of the pipeline connection in the dispensing device 100 and greatly reduces the space occupied by the multiple liquid discharge pipes 30, making the structure of the dispensing device 100 more compact and providing more space for the layout of other components, which helps to optimize the overall size of the dispensing device 100.

[0069] The drive assembly 40 is connected with the pump housing 10 and is used to drive the liquid (laundry treatment agent) to be extracted from the liquid storage cavity into the liquid suction nozzle 20, then into the pump housing 10, and then discharged from the liquid discharge pipe 30 to the laundry treatment cavity. The drive assembly 40 changes the pressure and flow rate of the fluid in the dispensing device 100 through rotation or reciprocating motion, thereby realizing the suction and discharge of the liquid.

[0070] In actual application, since the volume of each liquid storage cavity is limited, when the laundry treatment agent in one liquid storage cavity is used up, the controller cannot identify the empty state of the liquid storage cavity, and the dispensing device 100 is empty, which leads to insufficient actual dispensing amount of the laundry treatment agent, affecting the processing effect of the laundry.

[0071] To solve the above problems, please continue to refer to Figure 1The dispensing device 100 further comprises a fluid detection member 50 electrically connected to the controller. When the fluid detection member 50 detects that there is no fluid flowing in the drain pipe 30, it will immediately send a signal to the controller, indicating that the corresponding liquid storage chamber of the liquid suction nozzle 20 is empty. After receiving the signal, the controller will immediately stop the operation of the dispensing device 100, reducing the damage to the internal structure caused by the long-time empty suction of the dispensing device 100. The laundry treatment apparatus can further be provided with an alarm (not shown in the figure), which is electrically connected to the controller. The controller can control the alarm to issue an alarm to inform the user to supplement the laundry treatment agent, and display the specific no-remaining information of the liquid storage chamber on the control panel.

[0072] In the related art, the laundry treatment agent remaining amount sensing in the liquid storage chamber mostly relies on the scheme of float and door magnetic switch or probe, and such detection scheme system will increase with the increase of the types of laundry treatment agent, so as to realize the remaining amount alarm of different liquids. That is to say, if there are multiple chambers for containing laundry treatment agent, such as three chambers, a liquid level detector such as a float needs to be arranged in each chamber. Arranging a liquid level detector in each chamber not only increases the cost, but also occupies a certain chamber space, that is, arranging a liquid level sensor in the chamber will reduce the storage space in the chamber, affecting the liquid storage capacity of the chamber. In the embodiment, one fluid detection member 50 can detect the remaining amount of multiple different laundry treatment agents, greatly reducing the cost and complexity of the detection system, and also improving the volume of the chamber.

[0073] Exemplarily, the fluid detection member 50 comprises one of a flow meter and a capacitive sensor. If the flow meter detects that there is fluid flowing through the drain pipe 30, it will output a flow signal, indicating that there is fluid in the drain pipe 30. When the flow meter does not detect that there is fluid flowing through, it indicates that there is no fluid in the drain pipe 30. At this time, the flow meter can transmit an electrical signal to the controller. After the controller receives the signal of the flow meter, it is judged that the laundry treatment agent in the liquid storage chamber currently drawn by the dispensing device 100 is empty, and the work of the dispensing device 100 is stopped and an alarm is issued to remind the user to add. The flow meter can also monitor the fluid flow in the pipe in real time.

[0074] In some embodiments, the flow meter can be a thermal flow meter, which generally comprises a heating element and a thermistor. The heating element can heat the fluid flowing through, and the thermistor can measure the temperature of the heating element. When there is fluid flowing through the drain pipe 30, the fluid will absorb the heat emitted by the heating element, and the temperature measured by the thermistor will decrease. When the dispensing device 100 is empty, there is gas flowing through the drain pipe 30, and the gas absorbs less heat, so the thermistor will measure a relatively high temperature, that is, there is no fluid flowing in the drain pipe 30, and empty suction occurs.

[0075] The capacitive sensor monitors the fluid by detecting the change in capacitance between the two electrodes. The presence of the fluid changes the dielectric constant between the electrodes, thereby changing the capacitance value. When there is fluid passing through the detection area of the capacitive sensor, the capacitance value between the electrodes will change. The sensor detects this change, indicating that there is fluid in the drain pipe 30. If the capacitance value does not change, it indicates that there is no fluid between the electrodes, and the drain pipe 30 is empty, i.e. the laundry treatment agent in the storage chamber may have run out.

[0076] In some embodiments, the drain pipe 30 is a bellows pipe, which has good elasticity and can be bent and stretched to adapt to different installation spaces and angles, simplifying the installation process and avoiding installation difficulties caused by excessive rigidity of the drain pipe 30. It can also compensate for the displacement and vibration of the dispensing device 100 during operation, reducing the stress on the pipeline caused by the vibration of the dispensing device 100 during operation.

[0077] As shown in Figure 1 , the free end of the bellows pipe away from the pump shell 10 is provided with a drain nozzle 60. The provision of the drain nozzle 60 allows the operator to accurately control the discharge position of the liquid, enabling the discharge of the laundry treatment agent at a specific discharge point or avoiding direct impact of the liquid on a specific area. Moreover, the drain nozzle 60 is easy to install and disassemble, facilitating subsequent cleaning and maintenance.

[0078] Please refer to Figures 1-3 , the pump shell 10 comprises a main shell 11 and an upper cover 12 connected to the main shell 11. The upper cover 12 is connected to the main shell 11 and cooperates with the main shell 11 to form a common drain chamber 10a. The upper cover 12 can be arranged on the top of the pump shell 10 in the up-down direction. The common drain chamber 10a is formed by the cooperation of the main shell 11 and the upper cover 12, making the structure of the pump shell 10 more simple and compact.

[0079] Among them, the plurality of suction nozzles 20 are communicated with the drain pipe 30 through the common drain chamber 10a. Understandably, the design of the common drain chamber 10a integrates the drain paths of the plurality of suction nozzles 20 together, avoiding the occupation of excessive space by individually providing drain channels for each suction nozzle 20. This enables the dispensing device 100 to realize the extraction and discharge of multiple laundry treatment agents in a limited space, improves the space utilization rate, reserves more space for other components of the laundry treatment device, and helps to realize the miniaturization and functional integration of the device.

[0080] Please refer to Figures 2-4To improve the connection stability between the main shell 11 and the upper cover 12, the main shell 11 is further provided with a first fixing hole 11a, and the upper cover 12 is provided with a second fixing hole 12a; the pump shell 10 further comprises a fixing member 13 which is arranged in the first fixing hole 11a and the second fixing hole 12a, and can tightly connect the main shell 11 and the upper cover 12 together, providing sufficient connection strength and stability, so as to ensure that the main shell 11 and the upper cover 12 will not be loose or separated even if subjected to external forces such as liquid pressure and vibration during the operation of the dispensing device 100, thereby protecting the normal operation and service life of the dispensing device 100.

[0081] Understandably, the second fixing hole 12a is provided with a plurality of first fixing holes 11a which are arranged along the circumference of the upper cover 12, and a plurality of fixing members 13 are arranged in the plurality of second fixing holes 12a and the plurality of first fixing holes 11a one by one, and the arrangement of the plurality of fixing members 13 helps to improve the fastening effect of the connection of the upper cover 12 to the main shell 11, preventing displacement during the operation of the dispensing device 100 due to vibration, thereby maintaining the stability of the internal structure of the dispensing device 100.

[0082] Please refer to Figure 5 and Figure 6 , specifically, the first fixing hole 11a and the second fixing hole 12a are both threaded holes, and the fixing member 13 is a bolt, which can be easily and quickly fastened by being screwed through the corresponding threaded hole during assembly, thereby improving production efficiency. In subsequent use, the main shell 11 and the upper cover 12 can also be easily disassembled, which facilitates the inspection and maintenance of the internal structure and reduces maintenance costs and workload.

[0083] Please continue to refer to Figure 5 and Figure 6 , to effectively prevent the leakage of the laundry treatment agent in the common liquid discharge chamber 10a, the pump shell 10 further comprises a sealing member 14 which is arranged between the main shell 11 and the upper cover 12 to seal the gap between the main shell 11 and the upper cover 12, and can tightly fill the small gap between the main shell 11 and the upper cover 12 to form a reliable sealing barrier to prevent the laundry treatment agent in the common liquid discharge chamber 10a from leaking out of the gap.

[0084] Further, good sealing can also prevent external air, dust, impurities and the like from entering the interior of the pump shell 10, thereby protecting the internal laundry treatment agent from being contaminated, and the internal structure can also operate normally in a relatively stable environment, thereby prolonging the service life of the internal structure.

[0085] Specifically, the sealing member 14 can be a sealing ring, and the sealing ring is arranged to form a relatively closed space for the common liquid discharge chamber 10a, which helps to maintain stable liquid pressure in the pump housing 10 during operation of the dispensing device 100, so that the liquid can be extracted and discharged according to the predetermined flow rate and pressure.

[0086] After the dispensing device 100 extracts and dispenses a kind of laundry treatment agent, part of the laundry treatment agent will remain in the common liquid discharge chamber 10a, for example, after the dispensing device 100 extracts and dispenses the detergent, part of the detergent will remain in the common liquid discharge chamber 10a, and when entering the next program, for example, in the softening program, the softener extracted by the dispensing device 100 will enter the common liquid discharge chamber 10a, and the detergent remaining in the previous program will mix with the softener, which may cause poor texture and effect of the laundry treatment.

[0087] To solve the above problems, please refer to Figures 3-5 In some embodiments, the dispensing device 100 further comprises a cleaning structure, specifically, the upper cover 12 comprises a cover body 121 and a water inlet nozzle 122, the cover body 121 is connected to the main housing 11, and the water inlet nozzle 122 is connected to the cover body 121 and communicates with the common liquid discharge chamber 10a. Understandably, in the laundry treatment equipment, a water inlet pipeline is included, and the water inlet nozzle 122 can communicate with the water inlet pipeline, and after a kind of laundry treatment agent is extracted and dispensed, water flow will flow into the common liquid discharge chamber 10a to flush the residual laundry treatment agent in the common liquid discharge chamber 10a. In some embodiments, the dispensing device 100 further comprises a liquid outlet nozzle 123, and the mixed liquid of the washed water and the detergent can be discharged through the liquid outlet nozzle 123, and the liquid outlet nozzle 123 can communicate with the laundry treatment chamber, so that the mixed liquid is discharged into the laundry treatment chamber, fully utilizes the residual laundry treatment agent, reduces waste, and reduces the use cost of the user.

[0088] Flushing the common liquid discharge chamber 10a after each dispensing program can also prevent the residual laundry treatment agent from coagulating into lumps in the common liquid discharge chamber 10a, causing the liquid outlet nozzle 123 or the liquid discharge pipe 30 to be blocked, reducing the risk of blockage and prolonging the service life of the dispensing device 100.

[0089] It should be noted that in some embodiments, the liquid outlet nozzle 123 can be connected to the liquid discharge pipe 30, so that the mixed liquid in the common liquid discharge chamber 10a can be directly transported to the laundry treatment chamber through the liquid discharge pipe 30, without the need to arrange a separate pipeline connection to discharge the mixed liquid in the liquid outlet nozzle 123 into the laundry treatment chamber, thereby saving installation space, and being particularly suitable for space-limited occasions.

[0090] In some embodiments, the upper cover 12 further comprises a one-way valve (not shown) arranged at the water inlet nozzle 122 or the communication between the water inlet nozzle 122 and the cover body 121. In one aspect, when the common drainage cavity 10a needs to be flushed, the one-way valve is opened, and water flows into the water inlet nozzle 122, and when the common drainage cavity 10a does not need to be flushed, such as when the laundry treatment agent is extracted and dispensed, the one-way valve is closed, thereby achieving the sealing of the inside of the common drainage cavity 10a; in another aspect, it is ensured that water flow can only enter the common drainage cavity 10a from the water inlet nozzle 122 and cannot flow in the opposite direction, effectively preventing the backflow of the mixture in the common drainage cavity 10a to the water inlet pipeline during flushing, thereby preventing secondary pollution. This ensures that clean water is used for each flushing, improves the flushing effect, and completely removes residual laundry treatment agent.

[0091] Understandably, if the liquid outlet nozzle 123 is not connected to the drainage pipe 30, that is, the liquid outlet nozzle 123 is separately provided with a pipeline connected to the laundry treatment cavity, a one-way valve can also be arranged at the liquid outlet nozzle 123, when the dispensing device 100 is working, the laundry treatment agent enters the common drainage cavity 10a from the liquid extraction nozzle 20 and is discharged through the liquid drainage nozzle 60. At this time, the one-way valve on the liquid outlet nozzle 123 is in a closed state to prevent liquid from flowing out of the liquid outlet nozzle 123. When the flushing program is started, water flows into the common drainage cavity 10a from the water inlet nozzle 122, the one-way valve on the liquid outlet nozzle 123 is opened, and the mixture after flushing is discharged through the liquid outlet nozzle 123 and discharged into the laundry treatment cavity.

[0092] At present, the dispensing device 100 of the laundry treatment equipment can generally only realize the extraction and dispensing of single-path and double-path liquid. For an automatic dispensing laundry treatment agent device provided with three or even more liquid storage cavities, a more complex and larger structure is required to achieve the same, and in actual application, the installation space of the automatic dispensing member is relatively limited. When the volume of the dispensing device 100 increases, it will further limit the overall size of the automatic dispensing member, and ultimately cause the volume of the dispenser box to become smaller.

[0093] The driving assembly 40 provided in the embodiment is discussed taking three liquid storage cavities as an example. Understandably, the corresponding liquid extraction nozzle 20 is also provided with three, and the three liquid extraction nozzles 20 are respectively communicated with the three liquid storage cavities, so that the extraction and dispensing of three-path laundry treatment agents at different time sequences can be realized, the structure is simple, the occupied space is small, and when there are more liquid storage cavities in the laundry treatment equipment, the automatic dispensing member can be adaptively arranged.

[0094] Please refer to Figure 5 and Figure 6The driving assembly 40 includes at least two driving members 41, which are respectively arranged on both sides of the pump shell 10 along the first direction AA. In some application scenarios, the installation space of the delivery device 100 may be limited, but at the same time, higher driving capacity is required. Distributing the driving members 41 on both sides of the pump shell 10 can achieve higher driving efficiency in a limited space, making the overall design of the delivery device 100 more compact. It can be flexibly adjusted according to different installation environments and space requirements, improving the adaptability of the delivery device 100.

[0095] In some embodiments, the pump shell 10 includes at least one first plunger barrel 15 and a second plunger barrel 17 arranged along a second direction BB, the at least one first plunger barrel 15 and the second plunger barrel 17 are arranged along a first diagonal direction EE, the first plunger barrel 15 and the second plunger barrel 17 are both in communication with the liquid discharge pipe 30, and the second direction BB is arranged at an angle with the first direction AA; wherein the first direction AA can be the front-back direction of the delivery device 100, and the second direction BB can be the up-down direction of the delivery device 100. Arranging the first plunger barrel 15 and the second plunger barrel 17 along the up-down direction (second direction BB), and arranging the at least two driving members 41 along the front-back direction (first direction AA), this layout can make full use of the two dimensions of the space, making the structure of the entire delivery device 100 more compact. For example, in some miniaturized or integrated delivery devices 100, this design can effectively save space while meeting the requirements of high flow rate and high efficiency.

[0096] Among them, the driving member 41 is provided with two, two driving members 41 are respectively a first motor 411 and a second motor 412, the first motor 411 is used for driving liquid to enter the first plunger barrel 15 from one liquid suction nozzle 20, the second motor 412 is used for driving liquid to enter the second plunger barrel 17 from another liquid suction nozzle 20, and the first motor 411 and the second motor 412 are respectively arranged on both sides of the at least one first plunger barrel 15 along the first direction AA (i.e. the front-back direction of the delivery device 100). This means that from the perspective of top view, the first motor 411 is located on one side of the first plunger barrel 15, and the second motor 412 is located on the other side of the first plunger barrel 15, both of which are symmetrically distributed in space and adjacent to the first plunger barrel 15. This layout makes the two motors symmetrically distributed in space and form a compact structural relationship with the at least one first plunger barrel 15.

[0097] In some embodiments, the number of the first plunger barrels 15 is two, both of which are connected to the main housing 11 along a second direction BB, which can be the up-down direction of the dispensing device 100, each of the first plunger barrels 15 has a first piston chamber 15a in communication with the common liquid discharge chamber 10a, both of the first piston chambers 15a are in communication with the two liquid suction nozzles 20 respectively, and the first pistons 16 are arranged in the first piston chambers 15a. The first motor 411 is drivingly connected to the two first pistons 16, for driving the liquid to enter the corresponding first piston chamber 15a from the liquid suction nozzle 20 and be pumped into the common liquid discharge chamber 10a. Understandably, the embodiment can complete the extraction and dispensing of two routes of laundry treatment agent, and can control the extraction and discharge of the two routes of liquid at different time sequences, so as to ensure that each laundry treatment agent can be accurately dispensed at the appropriate time.

[0098] Further, the first motor 411 includes a motor body and two mutually reverse ratchet mechanisms, the motor body is located at one side of at least one first plunger barrel 15, the ratchet mechanism includes a ratchet assembly and a transmission gear meshing with the ratchet assembly, the two transmission gears are connected to the two first pistons 16 one by one, and the two ratchet assemblies are connected to the output shaft of the motor body. The ratchet assembly is an internally meshing ratchet transmission assembly, i.e. a gear device with an internal ratchet. The output shaft of the motor body has two rotation directions, i.e. clockwise and counterclockwise rotation directions, and the mutually reverse ratchet mechanisms mean that when the output shaft of the motor body rotates clockwise, the first ratchet assembly rotates while the second ratchet assembly remains stationary; when the output shaft of the motor body rotates counterclockwise, the second ratchet assembly rotates while the first ratchet assembly remains stationary. Understandably, when the first ratchet assembly rotates, the first transmission gear meshing therewith rotates, and similarly, when the second ratchet assembly rotates, the second transmission gear meshing therewith rotates. The first transmission gear and the second transmission gear drive the eccentric wheels of the two first pistons 16 to rotate respectively, so that the first pistons 16 can realize linear reciprocating motion. When the output shaft of the motor body rotates in one direction, it drives one of the first pistons 16 to reciprocate in the first piston chamber 15a along the second direction BB, thereby realizing the extraction of the laundry treatment agent from the corresponding liquid storage chamber of the liquid suction nozzle 20 and the discharge into the liquid discharge pipe 30.

[0099] The ratchet assembly comprises an inner meshing ratchet and a pawl disc with multiple pawls, the ratchet is fixed on the inner surface of a gear structure, the outer surface of the gear structure is engaged with a transmission gear, and the pawl disc is arranged on the output shaft of the motor body. When the output shaft of the motor body rotates clockwise, the first pawl disc pushes the first ratchet to rotate, correspondingly, the first gear structure drives the first transmission gear to rotate, and the second pawl disc is kept in a disengaged state with the second ratchet; when the output shaft of the motor body rotates counterclockwise, the second pawl disc pushes the second ratchet to rotate, and the first pawl disc is kept in a disengaged state with the first ratchet. This design ensures that the output shaft of the motor body can drive one of the two ratchet assemblies in different rotation directions, realizing independent control of the two first pistons 16.

[0100] Please continue to refer to Figure 5 and Figure 6 In some embodiments, the two first plunger barrels 15 are connected to the main housing 11 along the second direction BB, and the first piston cavities 15a extend along the second direction BB, wherein the two first plunger barrels 15 can be arranged side by side along the left-right direction, and the first piston cavities 15a of the first plunger barrels 15 all extend along the second direction BB, so that the two first plunger barrels 15 form a linear arrangement in the second direction BB. This arrangement makes the structure of the dispensing device 100 more compact. It should be noted that the arrangement of the two first plunger barrels 15 is not limited to strict left-right alignment, and the central axes of the two first plunger barrels 15 are parallel to each other, but the distance between them has a certain deviation along the first direction AA, that is, the arrangement of the two first plunger barrels 15 can be adjusted according to actual application requirements.

[0101] And along the first direction AA, the first motor 411 is connected to one side of the two first plunger barrels 15, and the first motor 411 is directly connected to one side of the two first plunger barrels 15, reducing the problem of too long transmission path, making the connection between the first motor 411 and the first plunger barrels 15 more direct and compact.

[0102] Further, the liquid extraction nozzles 20 of the dispensing device 100 are arranged extending along the first direction AA, and the first motor 411 is located below the liquid extraction nozzles 20. Placing the first motor 411 below the liquid extraction nozzles 20 can utilize the vertical space of the dispensing device 100, making the overall structure more compact and suitable for installation in space-limited situations. Due to the vertical arrangement of the first motor 411 and the liquid extraction nozzles 20, the installation density of the pump can be improved without increasing the floor area.

[0103] As Figure 7 , Figure 8 and Figure 9As shown, the pump housing 10 further comprises a second plunger barrel 17 and a second piston 18, the second plunger barrel 17 is connected to the pump housing 10, the second plunger barrel 17 has a second piston cavity 17a extending along a second direction BB, the second piston cavity 17a is in communication with another liquid suction nozzle 20, and the second piston 18 is arranged in the second piston cavity 17a.

[0104] The drive assembly 40 further comprises a transmission member 42, the transmission member 42 is connected with the second piston 18, and the second motor 412 is used to drive the second piston 18 to reciprocate in the second piston cavity 17a. By adding the second plunger barrel 17 and the second piston 18, cooperating with the second motor 412 and the transmission member 42, the extraction and injection of the third laundry treatment agent can be realized. This makes the injection device 100 capable of injecting three different laundry treatment agents at different time sequences, meeting more diverse washing needs.

[0105] The second motor 412 can receive precise control signals through the controller to realize precise driving of the second piston 18, ensuring that the extraction and injection amount of the laundry treatment agent is more accurate. The transmission member 42 comprises a driving gear 421 and a driven gear 422 engagedly connected, the driving gear 421 is connected to the output shaft of the second motor 412, and the driven gear 422 is connected to the second piston 18. Gear transmission is a kind of efficient mechanical transmission mode, which can directly convert the rotary motion of the motor into the linear reciprocating motion of the piston. This transmission mode reduces energy loss, improves transmission efficiency, and ensures that the movement of the second piston 18 is more stable and accurate.

[0106] The present application is not limited to this transmission mode. In other embodiments, the driving of the second piston 18 can also be realized by belt transmission or chain transmission. The specific choice of transmission mode can be flexibly adjusted according to the actual application scene and space limitation to meet different use needs.

[0107] Please continue to refer to Figure 7 , Figure 8 and Figure 9 , in terms of arrangement, one of the first plunger barrels 15 and the second plunger barrel 17 is arranged along the first direction AA, i.e. along the front-back direction, one of the first plunger barrels 15 and the second plunger barrel 17 is arranged adjacent to each other, and the first plunger barrel 15 and the second motor 412 are arranged along a second diagonal direction FF, the second diagonal direction FF is arranged intersecting with the first diagonal direction EE, and the included angle between the first diagonal direction EE and the second diagonal direction FF can be adjusted according to the specific application demand and space limitation. This included angle can be 90 degrees, when the first diagonal direction EE and the second diagonal direction FF form a 90-degree included angle, this layout can realize the optimal utilization of space, in other embodiments, the included angle between the second diagonal direction FF and the first diagonal direction EE can also be other angles.

[0108] In the prior art, the automatic dispensing member of the laundry treatment apparatus is generally arranged in the front-rear direction of the cabinet, i.e., in the first direction. With such an arrangement, the space behind the automatic dispensing member in the first direction is very limited. In order not to affect the volume of the liquid storage chamber and not to occupy too much internal space of the laundry treatment apparatus, some embodiments of the present application are arranged as shown in FIGS. 1A and 1B, wherein another first plunger barrel 15 is arranged in the first direction AA with the second motor 412, and the first plunger barrel 15 is also arranged in the first diagonal direction EE with the second plunger barrel 17, and the second motor 412 is arranged adjacent to the second plunger barrel 17. As can be understood, one side of the second plunger barrel 17 in the left-right direction is adjacent to the front-rear direction of another first plunger barrel 15, and a space is formed therebetween, which is used to arrange the second motor 412, i.e., the main body portion of the second motor 412 is arranged in the space. The second motor 412 can be arranged adjacent to the second plunger barrel 17 in the left-right direction and adjacent to the first plunger barrel 15 in the front-rear direction, i.e., from the perspective of the pump housing 10, the two first plunger barrels 15, the second plunger barrel 17, and the second motor 412 are arranged in two rows and two columns, so that the arrangement of the dispensing device 100 is more compact. With such an arrangement, the second motor 412 is arranged adjacent to the second plunger barrel 17, and the second motor 412 makes full use of the space between the plunger barrels in the first direction AA, so that the structure is more compact, and the internal space of the cabinet of the laundry treatment apparatus is saved, and the volume of the liquid storage chamber of the dispensing device 100 is also not occupied. Figure 9 and Figure 10

[0109] It should be noted that the second motor 412 includes a motor housing for protecting the internal components of the motor and providing structural support. It should be noted that the arrangement of the motor housing does not change the arrangement position of the main body portion of the second motor 412 described above. Specifically, the main body portion of the second motor 412 (i.e., the core driving components of the motor, such as the rotor and the stator) is located in the space between the plunger barrels described above, ensuring the compact layout of the dispensing device 100. The motor housing is partially covered on the second plunger barrel 17, so as to be arranged in space beyond the arrangement position of the main body portion of the second motor 412. Such a design aims to provide necessary mechanical protection and structural integrity, while not affecting the compact arrangement of the main body portion of the second motor 412.

[0110] Specifically, the motor body is arranged closer to the first plunger barrel 15 than the driving gear 421 and the driven gear 422. The position of the motor body can better utilize the space between the first plunger barrel 15 and the second plunger barrel 17, so that the overall layout is more compact. It can also avoid physical contact or spatial interference between the driving gear 421 and the driven gear 422 and the first plunger barrel 15 when they are running, thereby reducing potential mechanical interference problems.​

[0111] It should be noted that the first piston cavity 15a and the second piston cavity 17a both extend along the second direction BB, and the first plunger barrel 15 and the second plunger barrel 17 are connected below the pump housing 10, and the first piston 16 and the second piston 18 are driven to move up and down by the first motor 411 and the second motor 412, so as to realize the environment of negative pressure and positive pressure in the first piston cavity 15a and the second piston cavity 17a, that is, when the first piston 16 moves downward, the negative pressure exists in the first piston cavity 15a, and the liquid suction nozzle 20 connected therewith will suck the laundry treatment agent in the corresponding storage cavity into the first piston cavity 15a, so as to realize the extraction of the laundry treatment agent, and when the first piston 16 moves upward, the first piston 16 will pump the laundry treatment agent just sucked into the common liquid discharge cavity 10a, and the common liquid discharge cavity 10a will be delivered to the liquid discharge pipe 30 to flow out, so as to realize the discharge of the laundry treatment agent. Similarly, the second piston 18 has the same movement mode as the first piston 16.

[0112] Further, the first piston 16 and the second piston 18 are both provided with a sealing ring, which can be in sealing contact with the inner wall of the first plunger barrel 15 and the second plunger barrel 17, so as to realize the sealing of the first piston cavity 15a and the second piston cavity 17a, and prevent the leakage of the laundry treatment agent during the working process of the dosing device 100, thereby improving the reliability and safety of the dosing device 100.

[0113] Further, the axial direction of the second motor 412 is perpendicular to the second direction BB, and such a layout can effectively utilize the vertical space and reduce the space occupation in the horizontal direction. Such a design is particularly suitable for installation in a laundry treatment equipment with limited space.

[0114] Alternatively, the axial direction of the second motor 412 can be parallel to the first direction AA (i.e., the front-rear direction of the dosing device 100). Such a layout can further optimize the space utilization, so that the second motor 412 and the second plunger barrel 17 are arranged in the same plane, thereby reducing the thickness of the overall structure of the dosing device 100.
